You don't have a DD installation if your root file system is mounted on ad0s1a. You have a DD installation if your root file system is mounted on ad0a. In the DD case, the BSD disklabel in the 2nd sector is the one that's being used. In the non-DD case the BSD disklabel is in the 2nd sector of the first slice (sector 64 on the disk in the most common case). -- Marcel Moolenaar xcllnt@mac.com
